def get_pathname():
    """return the file that contains the indicated address"""
    retval = ''
    address = gdb.selected_frame().pc()
    maps = procmaps.from_pid(gdb.selected_inferior().pid)
    for m in maps:
        if address >= m.begin_address and address < m.end_address:
            retval = m.pathname
            break
